1. The problem statement, all variables and given/known data A 0.04-kg ball is thrown from the top of a 30-m tall building (point A) at an unknown angle above the horizontal. As shown in the figure, the ball attains a maximum height of 10 m above the top of the building before striking the ground at point B. If air resistance is negligible, what is the value of the kinetic energy of the ball at B minus the kinetic energy of the ball at A , that is calculate (K(B) – K(A))? 2. Relevant equations 3. The attempt at a solution I think K(B)- K(A)=K(B)=mgh is this correct?
